Because the oxygen in the air would cause it to combust rather than turn into coke (+coal gas).

How is coal turned into coke?
by heating the absence of air
What material is heated in an air-tight oven to make coke?
Coal
What is the difference between Hard coking coal vs soft coking coal?
Coke is made by heating coal in the absence of oxygen to about 2000 degrees Fahrenheit. Hard coking coal forms high-strength coke, while soft coking coal produces a lesser quality coke.
Does coke contain coal?
Coke is coal.
Which is hotter coal or coke?
coke is hotter than coal
What is metallurgical coke?
when bituminous coal is heated stronly in the absence of air,the volatile matter escapes out and the mass becomes hard,strong,porous and coherent which is called Metallurgical coke.
How is coal turned into coke?

What is green coke CBM?
Green = environmentally friendly (non-polluting). Coke = coal that has been heated in the absence of air (contains more energy than the same volume of coal). CBM = coal-bed methane (naturally occurring gas found in coal beds). It is a greenhouse gas if allowed to escape into the atmosphere, but if captured it can be used as a non-polluting fuel - probably to turn the coal into coke.

How is it produced coke from coal?
Coke is produced by the distillation of coal.
Which is hotter coal or coke?

How is coal converted to coke?
To convert coal into coke, the coal is burned in an oxygen-depleted environment. When this happens, the impurities of the coal are burnt up but the carbon remains. This is why coke is much lighter than coal.
What type of energy does a furnace use?
A furnace can be heated by fossil fuels like coal, coke, or natural gas, which is chemical energy or it can be electric.
Where coke fuel can be found?
Coke fuel is produced (in an industrial process) from coal which has been roasted in the absence of oxygen to drive off impurities consisting mostly of hydrocarbons and sulphur compounds. Coke fuel is almost pure carbon but will also contain trace amounts of ash, water and sulphur compounds.
